目的:探讨电离辐射知识宣传培训干预对基层医务人员电离辐射知识认知的影响.方法:选用问卷调查方式,对西安市地区10个乡镇卫生院基层医务人员共计181人进行电离辐射知识问卷调查,问卷内容包括基本知识、临床应用、日常防护、辐射危害和紧急处理5部分,选用Likert 3级评分法进行评分;对医务人员进行电离辐射防护知识培训;干预措施后进行二次问卷调查及评分,对比培训前后问卷调查评分情况.结果:培训干预前,基层医务人员电离辐射知识整体认知水平状态平均分为(28.09±13.17)分;培训干预后,平均分提高至(49.79±10.35)分,宣传培训干预前后电离辐射知识整体认知51～60分、41～51分和36分及格以上人数比较,差异有统计学意义(x2=119.795;P＜0.05).宣传培训干预后临床应用和基本知识得分略有提升,但无显著差异;日常防护、辐射危害和紧急处理得分分别提升至(11.39±0.35)分、(10.62±0.78)分和(8.65±1.22)分,宣传培训干预前后比较差异有统计学意义(t=2.18,t=1.87,t=1.56;P＜0.05).结论:电离辐射防护知识宣传培训等认知干预措施,能够明显提高基层医务工作者电离辐射防护意识,对提高日常防护意识及行为具有一定的促进作用.%Objective: To explore the effect of propaganda and training intervention about the ionization radiation knowledge for the cognition of these knowledge of elementary health care staff.Methods: A questionnaire survey about ionizing radiation knowledge was conducted on 181 medical workers in 10 township health hospitals in Xi'an.The contents of questionnaire included 5 parts that were basic knowledge,clinical application,daily protection,radiation hazard and emergency treatment.The Likert 3 grade scoring method was used to score the situation.And the training about ionizing radiation knowledge of protection was implemented for medical staff.The second questionnaires and scores were conducted after the intervention.And then the results of questionnaire survey and score between pre and post training were compared.Results: Before the training intervention,the average score of overall cognitive level of the ionizing radiation knowledge was(28.09±13.17),and the average score was increased to(49.79±10.35)after the training intervention.The difference of the number of three score segments(51-60,41-50 and 31-40)about the overall cognition of ionization radiation knowledge between pre and post interventions of propaganda and training were significant(x2=119.795,P＜0.05).The differences of clinical application score and basic knowledge between pre and post interventions of propaganda and training were no significant.And the scores of daily protection,radiation hazard and emergency treatment were increased to(11.39±0.35),(10.62±0.78)and(8.65±1.22)respectively,and the differences of them between pre and post interventions of propaganda and training were significant(t=2.18,t=1.87,t=1.56,P＜0.05),respectively.Conclusion: The cognitive interventions measurement of propaganda and training about preventive knowledge of ionization radiation can significantly improve the preventive awareness of elementary health care staff for ionizing radiation,and has a certainly promotion for enhancing the awareness and behavior of daily protection.
